IMISuJovEMENi IN HIDE-WORKING MACHINES.

The Schedule referred 'to in these Letters Patent and making part ofthe same.

I, MARCUS B. GO'ULD, ofthe city of Bud'alo,`iu

the county of Erie and State of vNew York, have infV vented an Improved Machine for Unhairing, Scouring, and Working Hides, of whichthe following isa vFigure 3 is a iront elevation.

Like letters of reference designate like parts in each of the figures.

a is the platform of any suitable construction, supported on' legs, and preferably provided with casters to enable it to be readily move-d.

A convenient size is about ten feet long and tive feet wide.

A skeleton-frame or carriage, l, provided with two racks', u u, on its under side, rests on and operated by tw'o pinions, c, attached to a shaft, @provided with a hand-crank, c.

Supported on casters, s, (reversed,) 4at each corner of this rac-k, rests the table d, ou which the hide tol he operated on is placed.. f

, The frame e e ,whichl supports the reciprocatingr heads is 'sho\vn in the drawing as attached to the rear end of the platform a, but practically, when the building will admit, it should besuspended from the frame or timbers overhead.

A series of crauks,"f f, operated crankat-the end of' the shaft, smounted in suitable 'bearings at the rear of the i'ame e.

m mare pitmen, attached to these arms orcranks required reciprocating movement to the heads which carry the working-tool at the opposite end thereof.

The 'cranksf are arranged so that whileone-half of the pitmen are moving in one-direction, the other halfare moving in the opposite, as shown.

At the front end. of the fIaule eis arrangeda crossbeam, i, vertically atljustable, and resting on spiral springs, t, wit-h hangers attached yto the under side, each consistingV of' two friction-rollers, o o, between which the pitmenreciprocate. This cross-beam is represented as. raised and lowered by a lever, le, with a cord and pulley, although a rack and pinion, or other suitable device, at the ends of the cross-beam, which works iuv suitable upright ways or post, maybe employed instead.

Projecting downward and forward from this beam are two or more spring-arms, a, provided with friction or pressure-rollers, n', lwhich press ou the hide on table d, and operate to hold itin Aplace thereon, while by a pulley or a f, whichshould be of suitable length to impart the they allow the table and hide together' to be freely .moved thereunder, as required.

The operation Aof my improved machine is as fol.-

".lhe cross-beam with its guided-hangers, o, impart tothe operating heads of the pitmen a combined re- -ciprocating and oscillating motion, so that the tools operate on the hide only during the movement in one direction. Y y

As one-half' of the series of tools actson the hide while'the other haltl is reversing, and fvz'ce versa, the resistance whichis opposed to the crank-shaft is distributed throughout its movement, and the action of the tools ou the hide, also distributed over the surface ot the latter, each alternate tool of the series,

-one-half in all operating at a time, thereby enabling 4tl1e-n1achineto`be more easily 'operated with less "strain on it and thehide.

By adjusting the cross-beam the pressure of the working-tools and rollers n' is regulated.

This'movemeut of the pitmen-heads has beelrpr` duced by other arrangements before the date of my invention..

1' The hideto be operated on is placed on the table el, which is readily moved in a circular direction on the casters s, while the rack-carrier, and table are' moved back and forth bythe crank c, as may be required. j v

The pitmen, or the free ends thereof, should be made slightly elastic, so as to yield as the tool passes over inequalities in the hide. v

' I am aware that a movable table for the hide, supported on a truck, is old and well known, and such I' do not claim.

to each other, and with the pitmen m and table d, so

. that one-half of the series of working-tools operates on' the hide at a time, as hereinbefore set forth.

2. .Lhe cross-beam provided with guide-:hangers o-o, arranged and operating'with the 'pitmeu m and working-tool m' at the free ends thereof, substantially as hereinbefore set forth. 3. The spring pressure-arms and rollers n n', combined and arranged. with the adj ustable` crossbeam t', pitmen m, and'movable table d, as and for the purpose hereinbei'ore set forth.

4. The arrangement with the platform a and movable table (l ot' the frame-carrier b, casters s, and racks andpinions u e, constructed and operating as. hereiubefore described.

5. The'arraugement with the cross-beam tof the supportingfsprings @adjusting-lever It, as and for the purpose hereiube-fore set forth.v
